Structure formation in steel 45 for railroad axles at high temperatures

Steel in Translation Aims and scope

Abstract

The growth kinetics of austenite grains in steel 45 is studied. The influence of the holding time of railroad-axle blanks at different temperatures is found to be nonmonotonic. Above 1150°C, with prolonged holding (>5 h), significant austenite grain growth is observed in the steel, with considerable variation in the final grain size.
